您链接的上一个问题来自2018年5月,是关于从ApachePOI
到3.17
版本的纯XSSFChart
内容。这已经过时了,因为apachepoi4.0.0
引入了新的xdf
东西
但是,直到现在,仅使用高级XDDF
类才支持设置标记颜色。标记具有与系列本身具有相同类型的填充特性的形状特性。因此,我们可以使用XDDFSolidFillProperties
和XDDFShapeProperties
作为行设置。但是为了获得标记,我们需要使用底层的ooxml-schemas-1.4
bean
例如:
...
series2.setMarkerStyle(MarkerStyle.DIAMOND);
series2.setMarkerSize((short)15);
XDDFSolidFillProperties fillMarker = new XDDFSolidFillProperties(XDDFColor.from(new byte[]{(byte)0xFF, (byte)0xFF, 0x00}));
XDDFShapeProperties propertiesMarker = new XDDFShapeProperties();
propertiesMarker.setFillProperties(fillMarker);
chart.getCTChart().getPlotArea().getScatterChartArray(0).getSerArray(1).getMarker()
.addNewSpPr().set(propertiesMarker.getXmlObject());
...
效果很好,但标记边框颜色仍设置为默认颜色。改变边框颜色也是一个类似的过程吗?是的,我知道了<代码>XDDFNoFillProperties noFill=新的XDDFNoFillProperties()代码>XDDFShapeProperties属性标记器=新XDDFShapeProperties()代码>propertiesMarker.setFillProperties(fillMarker)代码>XDDFLineProperties lineProperties=新的XDDFLineProperties()代码>lineProperties.setFillProperties(noFill)代码>propertiesMarker.setLineProperties(lineProperties)代码>
